Benefits of technology

The patent describes a method where a transmitting user equipment (UE) can prioritize the transmission of non-buffered data (also known as higher-priority data) over buffered data (also known as lower-priority data) during a communication session. This is done by identifying a subset of the higher-priority data within the non-audio data and transmitting it over a Quality of Service (QoS) channel, which is designed for audio traffic. This allows the target UE to prioritize the playback and processing of the higher-priority non-audio data. Overall, this results in faster processing times and better overall performance during the communication session.

Problems solved by technology

Thus, depending upon network conditions, the video packets may suffer packet loss, jitter, and / or delay.
This results in an inconsistent user experience.

Abstract

In an embodiment, a transmitting UE is engaged with a target UE in a communication session supported at least in part via a QoS channel on which audio traffic is primarily carried and a non-QoS channel on which non-audio traffic is carried. The transmitting UE obtains audio data and non-audio data for transmission to the target UE during the communication session, and identifies a subset of higher-priority non-audio data within the obtained non-audio data. The transmitting UE transmits a stream of packets including both the audio data and the subset of higher-priority audio data over the QoS channel instead of the non-QoS channel based on the identification. The target UE receives the stream of packets on the QoS channel, and the target UE identifies and extracts the audio data and the higher-priority non-audio data. After extraction, the target UE plays the audio data and processes the higher-priority non-audio data.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]Embodiments of the invention relate to selectively transferring high-priority non-audio data over a Quality of Service (QoS) channel.[0003]2. Description of the Related Art[0004]Wireless communication systems have developed through various generations, including a first-generation analog wireless phone service (1G), a second-generation (2G) digital wireless phone service (including interim 2.5G and 2.75G networks) and third-generation (3G) and fourth-generation (4G) high speed data / Internet-capable wireless services. There are presently many different types of wireless communication systems in use, including Cellular and Personal Communications Service (PCS) systems. Examples of known cellular systems include the cellular Analog Advanced Mobile Phone System (AMPS), and digital cellular systems based on Code Division Multiple Access (CDMA), Frequency Division Multiple Access (FDMA), Time Division Multiple Access (TDMA), ...
